Observation footprints are shown in Fig. 1. Orbit indicates satellite flight direction (A ascending, D descending). Date shows acquisition date of master data (above) and slave data (bottom). B_perp represents perpendicular baseline between master and slave data. All PALSAR-2 data are derived using stripmap mode. Footprint width of SAR data depends on the incident angle. Pix. spacing indicates the spatial resolution for range (Ran.) and azimuth (Az.) direction
